ELLSWORTH E. FLORA, OF CHICAGO, ILLINOIS, ASSIG'rNOR TO SIMPLEX METAL-:BOUND BOX COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.

TOOL FOR USE IN FASTENING METAL STRIPS.

To (LZ2 whom it may concern:

13e it known that I, ELLswon'rI-r E. FLORA, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Im provement in Tools for Use in Fastening Metal Strips, of which the following is a specification.

My object is to provide a sirable tool for use, crimping the elges of metal-strips in producing the fastener for the strips described and claimed in my application for Letters Patent filed concurrently herewith and bearing Serial Number 605,542. The fastener or fastening means referred to is, more especially, adapted for securing together the ends of metal-straps employed upon boxes, bales and similar packages and consists of a sleeve through which the strips or strapends are passed to overlie one another and having one or more gaps in which the marginal portions of the strips are exposed and into which the said portions are forced or bent laterally out of their original alinement to present shoulders to each other and to the margin al walls of the gaps, thereby securing the parts together.

The purpose of the present invention is to provide a handy tool of peculiar construction adapting it for crimping or bending the marginal portions of the strips in the sleeve gaps, for the purpose stated.

ln the accompanying drawing-Figure l is a side elevation of my improved tool; Fig. 2, a section on line 2 in Fig. 1 through the jaws of the tool, the view also illustrating the manner in which the tool is applied to bend or crimp the opposite edges of the metal-strips in the gaps of a sleeve to secure them together; Fig. 3, a broken perspective view of the sleeve and metal-strips, or strapends, before they have been operated upon by the tool; and Fig. 4, a similar` view of the same parts after they have been operated upon by the tool.

The tool is of the general form of a pair of pliers having handles 5, 5 and jaws 6, 6, the parts being pivoted together at 7. Each simple and demore especially, in

of the aws 6 is formed with a gutter 8 having side-faces convergent toward the gutterbottom, and having also a projection or crimping-wedge 9 extending transversely across the gutter. The tip of each crimping wedge is rounded to render it blunt.

The strips 10, 11 shown may be the ends of a box-strap which it is desired to secure together. The strap ends are passed through a metal sleeve 12 provided at its opposite sides with gaps 13. The bore of the sleeve is no larger than necessary to permit the strap-ends to pass through it from opposite directions, so that they will overlie one another with their edge-portions crossing the gaps 13, as indicated, in Fig. 3. The tool is applied to form the bends or crimps 14 in the strips or strap-ends by causing it at its gutters 8 to pass over and receive the opposite edges of the sleeve and its wedges 9 to engage the strip-edges in the gaps 13. Pres sure is then applied to the handles 5 to squeeze and bend or crimp the edges of the strips in the gaps, as shown at 14, to produce shoulders or enlargements, which are presented to each other and to the edges of the gaps to prevent relative sliding of the parts and thus fastening them securely together.

lVhat I claim as new and desire to secure by Letters Patent is- 1. A tool for fastening metal strips having pivoted jaws provided with extended wedge-shaped terminals formed by transverse sleeve-receiving grooves, and indenting projections extending across said grooves, for the purpose set forth.

2. A tool for fastening metal strips having pivoted jaws provided with wedgeshaped terminals formed by transverse sleeve-receiving grooves, and. blunt wedgeshaped indenting projections extending across said grooves, for the purpose set forth.
